Ryomen Sukuna is the main antagonist of Gege Akutami's Jujutsu Kaisen, a manga first serialised in 2018 and adapted into an anime in 2020. Fuga, meaning open, is the word he speaks to release his flame-based cursed technique, distinct from his slashing attacks Dismantle and Cleave. As the series grew popular, manga readers and anime fans isolated the single word as a recognisable cue on soundboards and in fan edits, where its brevity and the character's reputation make it instantly identifiable even out of context.

Ryomen Sukuna saying Fuga from Jujutsu Kaisen, the short voice line used as an anime sound effect for attacks, edits and dramatic reveals in videos.
This is Ryomen Sukuna's terse declaration of Fuga in Jujutsu Kaisen, his open flame technique, delivered in a low, calm and menacing voice. The clip is only the single word, stretched just over a second, but the controlled delivery makes it feel like a warning before an attack lands. Sukuna does not shout, and that restraint is why the moment hits so hard in the manga and anime, carrying authority, cruelty and total confidence. In edits it instantly signals danger, power and a villain taking control of a fight.
